Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and tolerance Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between allows breeder formulate indirect selection strategies. In this study, we investigated phenotypic, genotypic, environmental correlations agronomic plants naturally infected P. pachyrhizi, identified would be useful indirectly...

Abstract: The objective of this work was to evaluate the physiological and production parameters soybean (Glycine max) cultivars determinate indeterminate growth habits, in three levels soil moisture. Three habit growth, at beginning reproductive stage, were subjected moisture: control, moisture field capacity; moderated, 50% control level; severe, 25% level. Leaf gas exchange, xylem-water potential, chlorophyll content, a fluorescence, plant dry matter, grain yield per evaluated. showed...

Soybean (Glycine max L. Merr.) adaptation to new environments has been hard predict based on maturity group. The aim of this study was evaluate the performance 14 soybean genotypes, from Breeding Program Federal University Uberlandia, in their adaptive capacity and seed yield stability at 3 locations 2 growing seasons. For adaptability analysis Toler Centroid methods were used; 5 genotypic groups identified first whereas 4 latter. By method group A composed by UFU-001, UFU-003, UFU-0010,...

A competição entre os recursos ambientais, imposta pela comunidade infestante, afeta o crescimento, produtividade e qualidade final da soja, prejudicando a colheita, por competição, que aumenta custo operacional. Outro fator relevante interferência das plantas infestantes é estas podem ser hospedeiras de patógenos pragas, dificulta seu controle. Este trabalho teve como objetivo avaliar desempenho agronômico duas cultivares soja sujeitas à infestantes. O experimento foi conduzido na área...
